Kinoma HD (left) and Kinoma Element
Clearly, some price breaks would be expected for these much simpler devices, which lack the more extensive I/O and QVGA touchscreen of the still available Create. Yet, considering that the HDMI stick form-factor Kinoma HD, for example, runs a dual-core processor, up from the single-core chip on the Create, the $25 price is impressive.
The Kinoma HD “scriptable stick” connects wirelessly to IoT devices, iOS and Android handhelds, cloud services, and content from web-based apps, says Marvell. The HD device runs Linux on one of Marvell’s Armada 1500 family of SoCs, in this case a dual-core, 1.2GHz Marvell Armada 88DE3006. This is an apparently new upgrade to the similarly 1080p ready Armada 1500-mini (88DE3005). The small-footprint 88DE3005 SoC is the heart of Google’s Chromecast stick computer.
No dimensions were listed for the “thumb-sized” Kinoma HD, which looks to be a bit smaller than the 72 x 35mm Chromecast. Marvell’s stick is equipped with 256MB of RAM, and offers the 802.11ac flavor of WiFi. The only ports are an HDMI output and a micro-USB input for power.
The Kinoma Element, meanwhile, runs the open source FreeRTOS on Marvell’s 200MHz, WiFi-enabled MW302 Cortex-M4 microcontroller. The small desktop device is equipped with 802.11n WiFi, as well as a pair of 8-pin expansion connectors that can connect with sensors, lights, motors, and actuators. The 16 programmable pins provide serial, digital, analog, I2C, and PWM interfaces.
Although there was no specific mention of the Kinoma Studio desktop IDE, which ships with the Create, we imagine it’s available for the new devices as well. When it first shipped, Kinoma Studio supported only Windows and Mac desktops, but as of June 19, a complete Linux version was released with the same capabilities.
At CES in January, Marvell announced another Linux-based device called the 3D Printer SoC Solution, billed as the first Linux-based hardware/software development kit for 3D printers. This kit is built around a new, 533MHz 88PA6120 ARMv7 SoC, and also includes four crypto coprocessors, plus dual real-time MCUs for enabling customizable precision motion control. A PDF datasheet has been posted on Marvell’s Printer page, but it’s unclear if the product is shipping.
